摘要
无线Mesh网络是一种架构式多跳无线网络,具有结构灵活、快速部署、自组织和自愈合等优点,具有广泛的应用前景。通过采用ns-2仿真软件对基于IEEE 802.11 MAC协议和AODV路由协议的无线Mesh网中实时数据业务的数据传输进行建模与仿真,分析了Mesh网络中数据流经过的传输跳数与吞吐率的关系,以及MAC层RTS/CTS、重传次数以及MAC层和路由层相互作用对无线Mesh网中实时数据业务性能的影响,指出了提高无线Mesh网中实时数据业务性能的所需要的改进方向。
Wireless Mesh network is an architectural multi-hop wireless network,and for its advantages of flexible architecture,rapid deployment,self-organization and self-healing,has broad and promising application prospects.The real-time data service in wireless Mesh network is modeled and simulated with ns-2 simulation software and IEEE 802.11 MAC and AODV routing protocol.The relationship between the transmission of data flow through the hops and throughput,the impacts of RTS/CTS,retransmission times in MAC layer and the interactions of MAC layer and routing layer on the performance of real-time data service are analyzed,and the potential approaches to enhanceing the performance of real-time data service in wireless Mesh network are discussed.
